1. A remote authorization verification system comprising:
- a central device including;
data input and output facilities for communicating user authorization verification data with a plurality of hand held, pocket size remote units and providing an output indication of user authorization status,a memory for storing predetermined user authorization verification data for comparison purposes including coding keys, each of which is synchronized with the coding key of each of said remote units anddata comparison facilities for comparing user authorization verification data received from said plurality of hand held, pocket size remote units with user authorization verification data stored in said memory for determining whether authorization exists; and
a plurality of hand held, pocket size remote units providing data communication with said central device via conventional telecommunications devices, said pocket size remote units each including;
information input keying means, for receiving a user memorized password code,verification means for confirming receipt of a correct user memorized password code assigned to each individual remote unit and means for providing an enabling output in response to receipt of said correct password code by said verification means, a memory for storing a coding key, andenciphering means operative when enabled by said enabling output, and in accordance with said coding key for providing an enciphered verification code for transmission to said central device for indicating the authorized status of a user,each of said remote units being operative to produce an enciphered verification code by employing the coding key stored in its memory in response to the password code inputted through its information input keying means, said verification code being different for each entry of said correct password code.
